Skin antisepsis

Background: Although studies are rife on preoperative skin antisepsis, little is known about what surgeons in Nigeria practice. Objective: To describe the pattern of practice of skin antisepsis prior to skin incision among surgeons in select tertiary hospitals in Nigeria. Methods: This was a questionnaire-based descriptive cross-sectional survey involving surgeons and surgeons in training in the departments of surgery, obstetrics and gynaecology (O&G), otorhinolaryngology (ENT), and oral & maxillofacial surgery (OMS) of 26 select tertiary hospitals from all six geopolitical zones in Nigeria...

Bloodstream infections associated with vascular access procedures pose a serious risk to patients that can be reduced by better standards of aseptic technique. The objectives of this roundtable of experts were to achieve a consensus on how to improve skin antisepsis in hospital, improve training, competency, compliance and consistency in skin antisepsis, review the role of devices in improving skin antisepsis, identify methods to improve skin antisepsis integrated with the Aseptic Non Touch Technique (ANTT®) approach, and identify challenges to the implementation of the panel's recommendations...

INTRODUCTION: Patients with invasive medical devices are at high risk for infection. Skin colonization is the initial stage of these infections, leading to the recommendation of practices requiring disinfection using antiseptics. Microbial communities playing a major role in skin health could be impacted by antiseptic procedures. AIM: To characterize and compare the bacterial communities of skin samples from patients before an antisepsis procedure, and after removal of the medical device itself, according to the nature of the antiseptic molecule (povidone iodine or chlorhexidine)...

Background: Surgical site infection (SSI) is an adverse event that can lead to increased pain, increased cost, risk of death, and decreased patient satisfaction. Studies have investigated the best solutions to prevent SSI. Chlorhexidine has been suggested as the most efficacious antiseptic. However, scant data exist on application of antiseptic solutions and effectiveness of concentric versus back-and-forth strokes. Because a specific method may result in better outcomes, we aimed to review the literature to compare these two techniques...

OBJECTIVE: To determine skin reaction, post-treatment reduction (immediate effect), and 1 hour post-treatment reduction (sustained effect) of aerobic bacterial colony forming units (CFU) following three antiseptic protocols in cattle. STUDY DESIGN: Prospective, randomized experimental study. ANIMALS: Eighteen cows. METHODS: Three sites in each paralumbar fossa were clipped and randomly assigned to one of three treatment groups: 5 minute 4% chlorhexidine gluconate scrub (CHG); 90 second 80% ethanol scrub (ET); 90 second 70% isopropyl alcohol scrub (IPA)...

BACKGROUND: Normal skin flora and suboptimal skin antisepsis are the primary drivers of healthcare-associated infections (HAIs). Antimicrobial persistence of preoperative skin preparation is necessary to limit microorganisms on the skin and help minimize their entry into an incision or device-insertion site after application. AIM: To assess the antimicrobial persistence of two preoperative skin preparation solutions. METHODS: A randomized, single-centre, partially blinded, clinical study was conducted in 103 healthy volunteers to evaluate the persistent antimicrobial properties of BD ChloraPrep™ (2% w/v chlorhexidine gluconate [CHG] + 70% v/v isopropyl alcohol [IPA]) and BD PurPrep™ (8...

Candida auris is an emerging healthcare-associated infection that can easily cause dissemination in hospitals through colonizing the skin and contaminating environmental surfaces, especially in Intensive Care Units (ICU). Difficulties with identification of this organism, uncertainty about routes of transmission and antifungals resistance have impacted significantly outbreak detection and management. Here, we describe our experience with colonization/infection of C. auris among critically ill patients, admitted to a referral ICU of a University Hospital, in a transitional period (July 2021-March 2022) between management of non-COVID-19 and COVID-19 patients due to the reconversion of the ICU between two waves...

OBJECTIVE: Ventriculoperitoneal (VP) shunt insertion and revision surgeries are some of the most common procedures that are performed by neurosurgeons. Shunt infections within the adult population are associated with significant morbidity and mortality and rates remain high. The objective of the current study was to use quality improvement (QI) methodology to create a standardized infection prevention bundle aimed at reducing the rate of shunt infections. METHODS: A prospective, single-center, single-surgeon QI study was undertaken...

BACKGROUND: Surgical site infections (SSIs) in children represent a common and serious postoperative complication. Surgical skin preparation is an essential preventive measure in every surgical procedure. The most commonly used antiseptic agents for surgical skin preparation are chlorhexidine gluconate and iodophors in alcohol-based solutions. In adult patients the use of chlorhexidine-containing antiseptic solutions for preoperative skin preparation has been advocated to reduce SSI rates...

BACKGROUND: The approval of ethanol by the Biocidal Products Regulation has been under evaluation since 2007. This follows concern over alcohol uptake from ethanol-based hand rubs (EBHR). If ethanol is classified as carcinogenic, mutagenic, or reprotoxic by the European Chemicals Agency (ECHA), then this would affect infection prevention and control practices. AIM: A review was performed to prove that ethanol is toxicological uncritical and indispensable for hand antisepsis because of its unique activity against non-enveloped viruses and thus the resulting lack of alternatives...

Background and Objectives: Wound healing is commonly associated with critical bacterial colonization or bacterial infection, which induces prolonged inflammation, resulting in delayed re-epithelialization. An appropriate wound dressing requires a humid environment, which also functions as a barrier against bacterial contamination and will accelerate a regenerative response of the wound. Silver sulfadiazine (SSD) is used to prevent wound infection. Hyaluronic acid (HA) is an extracellular matrix component involved in tissue regeneration...

OBJECTIVE: The purpose of our study was to compare the cost of surgical site skin preparation using ChloraPrep™ (2% chlorhexidine gluconate [CHG] and 70% isopropyl alcohol [IPA]) with skin cleansing using Betadine® Surgical Scrub and Betadine® 5% solution (povidone-iodine [PVI]) in total hip arthroplasty (THA). HYPOTHESIS: The hypothesis was that the ChloraPrep™ skin disinfection protocol reduces the cost of perioperative antisepsis. METHODS: A prospective database was created for all THAs performed at our university hospital between November 1st, 2020, and December 31st, 2020...

BACKGROUND: Preoperative skin antiseptics are used prior to surgery to reduce the risk of surgical site infection (SSI). There is debate as to which is the most effective. The aim of this network meta-analysis (NMA) is to compare the effectiveness of different skin preparations at reducing SSIs in patients undergoing incisional surgery. METHODS: The study protocol was published in PROSPERO (CRD4202181599) a priori with predefined search terms and inclusion/exclusion criteria...

PURPOSE: Chlorhexidine digluconate (CHG) is a first-line antiseptic agent typically applied to the skin as a topical solution prior to surgery due to its efficacy and safety profile. However, the physiochemical properties of CHG limits its cutaneous permeation, preventing it from reaching potentially pathogenic bacteria residing within deeper skin layers. Thus, the utility of a solid oscillating microneedle system, Dermapen®, and a CHG-hydroxyethylcellulose (HEC) gel were investigated to improve the intradermal delivery of CHG...

The skin acts as a physical barrier to protect the body from the external physical and chemical environment. When skin is infected, the outer epidermal barrier is compromised and colonized with microbial growth. Wound infection presents an immense burden on healthcare costs and decreased the quality of life for patients. The topical application of nanoemulsions (NE) at pathological sites offers the potential advantage of direct drug delivery to the skin including the potential for follicular targeting. This may have application in the improvement of skin antisepsis...

Recurrent bacterial infection is a major problem that threatens the tissue repair process. However, most current therapeutic strategies fail to deal with management of the overlap dynamics of bacterial killing and tissue repair. Here, in accord with the different responses of eukaryotic and prokaryotic cells to electric potential, we developed high performance photoelectric BiOCl nanosheets that dynamically switch between conditions that favor either tissue regrowth or antibacterial microenvironments due to light stimulated and bi-modal switching of their surface electrical polarization...

BACKGROUND: Although there is a rationale supporting that preoperative showering with 2% or 4% chlorhexidine gluconate (CHG) would decrease skin bacterial colonization, there is no consensus that this practice reduces the risk of surgical site infection (SSI). OBJECTIVES: Analyze the skin concentration of CHG after preoperative showering associated with the traditional skin preparation with CHG 4% for breast surgery. METHODS: Randomized controlled trial that included 45 patients, all candidates for augmentation mammaplasty, allocated into three groups (A: no preoperative showering; B: one preoperative showering; C: two preoperative showering with CHG 4%) in a 1:1:1 ratio...

BACKGROUND: Burns are traumatic wounds that occur when skin is exposed to an amount of energy greater than its maximum dissipation capacity. Alcohol, because it fuels flames and its vapor can cause an explosion, is one of the most common causal agents of burns in Brazil. In late 2019, the COVID-19 pandemic caused a sudden and substantial increase in the use of 70% alcohol (w/v) for antisepsis. OBJECTIVES: To analyze the epidemiological characteristics of alcohol burns during the COVID-19 pandemic in participating Burn Treatment Centers, as well as the severity and treatment of these burns...
